I've told this story before here, but it fits the thread.
Several years ago, I was on the way to deliver the baccalaureate address at a rural high school. I had stopped behind a car waiting to make a left turn, and noticed in my rear-view mirror that a car was closing fast. He saw me too late and slammed into the rear of my car. I was shaken, but not hurt. I looked up and the car in front of me was gone.
Each of us got out of our cars to inspect the damage. I expected to see a bashed in trunk and a bashed in grill.
There was neither. Our bumpers had matched perfectly. They had neither dents nor scratches. There was no damage to either car. And none of us was injured.
After I spoke, I headed home and called my fiance to tell her what happened. She broke into tears. "Don't cry, everything is okay," I said.
"That's not what I'm crying about," she said. "What time did this happen?"
"About 6:45," I answered.
"Let me tell you what happened. I was vacuuming the carpet when I heard an audible voice say 'stop and pray for Tom.' I blew it off as something I imagined, when I heard it again, this time more insistent. So I stopped, fell to my knees by the couch and began to pray. 'Lord, I don't know what to pray for, but please take care of Tom.'
At the very moment of the rear-ender, she was praying for my safety.
She never heard that audible voice again, although on more than one occasion she has been strongly moved to pray for someone or some thing.
I have to confess that I'm a bit leery when someone claims "God told me this or that," or "God spoke to me." Or, "God told me to tell you so-and-so."
Maybe those folks are more spiritually sensitive than I am, but somehow I don't think God is going to tell someone else what I ought to do when He could just as easily tell me.
